Answer:
<h2>(2,4)</h2>
Step-by-step explanation:
The given function is
Where , and .
The vertex is at , which is defined as and . So, replacing values, we have
Then,
So, the vertex is at .
Remember that the minium or maximum value of a quadratic function is defined by its vertex. In this case, it represents a minimum at (2,4).
Answer:
Here,
slope (m)=3
y-intercept (c)= -5
Now,
The equation of the line;
or,y=mx+c
or,y=3x-5
or,0=3x-y-5...is the required equation.
For this question you should first add +1 on both sides of the equation so you will have:
y^2 = 80 + 1
y^2 = 81
so the square root of 81 is 9 and -9 so y equals to 9 and -9 :)))

Answer:
8i+8j
Step-by-step explanation:
3i+4j+5i+4j
i(3+5) + j(4+4)
Therefore 8i +8j

Answer:
ab = 280
or
a = 280/b
Step-by-step explanation:
Inverse variation is of the form
xy = k
Since we have a and b as our variables
ab = k
20 *14 = k
280 = k
ab = 280
Sometimes they write it as
a = 280/b
